Do 4Runners have a lot of problems?

In brief, Toyota 4Runners are widely regarded as durable and reliable, with relatively few chronic problems. Individual experiences vary by model year, mileage, and how well the vehicle has been maintained. Aging examples can show issues common to older SUVs, but overall reliability remains strong for most owners.

Reliability snapshot by generation

Below is a focused look at reliability patterns across the main eras of the 4Runner, highlighting typical concerns and what tends to wear out as miles accumulate.

Older generations (1989–2002): rust, wear and drivetrain basics

Owners of early 4Runners often report that high-mileage examples, especially in climates with road salt, can show frame rust and general wear on suspension and drivetrain components. The 4WD system is capable, but its aging parts—such as shocks, bushings, and transfer-case seals—require attentive maintenance.

• Frame and underbody rust risks in older models from rust-prone regions; inspect for corrosion and structural integrity on high-mileage units.


• Suspension wear (ball joints, tie rods, bushings) and steering components tend to degrade with mileage and time.


• Transfer-case and 4WD actuator issues can appear as the system ages, though problems are not universal if the vehicle has been properly serviced.

In short, these early models can be exceptionally durable when well cared for, but rust and wear are common concerns for buyers of aged examples.

Modern generations (2003–present): durability with maintenance emphasis

In newer versions, Toyota refined the powertrain and chassis, resulting in strong overall reliability. Typical concerns tend to involve aging electronics and components tied to high-mileage use, plus routine maintenance items like cooling system parts and exhaust hardware on some engines.

• Most engines prove reliable, but some high-mileage units report exhaust-manifold-related wear or stud issues on certain V6 configurations, which are fixable with service.


• Cooling-system wear (radiator hoses, water pump, thermostat) can appear as miles add up; regular coolant maintenance is advisable.


• Electrical and HVAC components (window regulators, switches, A/C compressors) may degrade in older vehicles or those with heavy use.

Overall, modern 4Runners tend to hold up well with routine maintenance, and they generally outperform many rivals in long-term durability.

Reliability ratings, recalls, and owner sentiment

Here is how independent sources and official recall data typically describe the 4Runner’s reliability, along with what buyers should verify before purchase.

Across generations, reliability is commonly regarded as above average for the class, with notable emphasis on long-term durability and strong resale value. Recalls have occurred over the years for various safety and component issues; the exact open recalls can be checked by VIN through NHTSA or Toyota’s site.

• Consumer and industry ratings frequently place the 4Runner in the reliable-to-very-reliable range within the midsize SUV segment, particularly for well-maintained examples.


• Recall activity has touched several model years, spanning airbags and other safety-related components; always verify whether a used 4Runner has any open recalls and have them addressed.


• Well-documented maintenance history, including timely oil changes, cooling-system service, and drivetrain upkeep, correlates strongly with better long-term performance.

In short, while recalls exist and older units may show aging components, the overall reliability profile remains favorable for most owners who stay on top of service and maintenance.

What to inspect when buying a used 4Runner

For prospective buyers, a careful inspection and a complete service history are essential to minimize surprises with a used 4Runner.

• Frame and undercarriage: check for rust, corrosion, and signs of structural repair, especially on older models and in salt-prone areas.


• Drivetrain and 4WD system: assess transfer-case seals, differential leaks, CV joints, and listen for unusual drivetrain noises when testing 4WD modes.


• Engine and cooling: look for oil leaks, coolant leaks, and verify maintenance records for cooling-system components and the timing chain if applicable to the engine.


• Suspension and steering: inspect bushings, ball joints, tie rods, shocks/struts, and alignment to gauge wear and fault potential.


• Electricals and interior: test electronics, windows, climate control, and verify there are no outstanding fault codes.

A thorough pre-purchase inspection by a qualified mechanic and a review of maintenance and recall history (via VIN) are highly recommended before buying.

Summary

Overall, the Toyota 4Runner is renowned for longevity and reliability, especially when it has received regular maintenance. It is not immune to aging-related issues, but most problems are manageable with proper care and timely repairs. For buyers, prioritizing well-documented service history, rust-free frames, and a clean maintenance record will yield a dependable, long-term ownership experience.

What year of 4Runner to avoid?

Years of Toyota 4Runner to avoid include 2003-2005, known for severe frame rust and head gasket issues, and 2001-2002, which are also prone to head gasket problems and early rust. Other problematic years are 1988-1989 and 1990-1995 (especially with the 3.0L V6), which can have head gasket failures. Additionally, the 2015 model should be approached with caution due to airbag issues. 
Early generations

• 1988-1989: These first-generation models are known for head gasket failures, especially those with the 3.0L V6 engine. 
• 1990-1995: Similar to the earlier years, the 3.0L V6 is prone to head gasket issues. Rust is also a major concern for frames and suspension components. 

Third and Fourth generations 

• 2001-2002: These models suffered from engine problems, including head gasket failures, and were the first to show significant signs of frame rust. 
• 2003-2005: This is arguably the most problematic generation. Owners report widespread severe frame rust, head gasket failures, cracked dashboards, and problems with the anti-lock braking system. The 2004 model year, in particular, has a high number of complaints for these issues. 

Fifth generation

• 2015: While generally considered reliable, this model year is notable for its airbag defects, where they did not deploy consistently. 

Other potentially problematic years

• 2010: This year experienced electrical faults and glitches with dashboard lights and sensors. 

What is the life expectancy of a Toyota 4Runner?

The Toyota 4Runner is a testament to Toyota's commitment to quality and reliability. Many owners report their vehicles reaching over 200,000 miles, with some even surpassing 300,000 miles. This longevity is attributed to the 4Runner's robust engineering, high-quality materials, and a design that prioritizes durability.

Do Toyota 4Runners have any issues?

Common problems: Some of the most common problems reported with the 2025 Toyota 4Runner include transmission concerns, engine performance issues, and interior design complaints.
